IMPROVEMENT IN TREADLES FOR MACHINERY.

Specification forming part of Letters Patent N 0. 169,692., dated November 9, 1875; application filed May 1, 1875.

To all whom it may concern:

Be it known that I, ANDREW N. HAGERTY, of West Alexander, in the county of VVashington and State of Pennsylvania, have invented a new and Improved Treadle Mechanism, of which the following is a specification:

Myinvention consistsot' an auxiliary treadle and connecting-rod, in combination with the.

main treadle and connecting-rod, to work a pawl for starting the machine by a ratchetwheel, so as to insure the turning of it in the right direction, and to avoid the necessity of starting the balance-wheel by hand, thus leaving both hands free for managing the work.

Figure 1 is a side elevation of a treadle-motion of my invention, and Fig. 2 is an elevation taken in a plane at right angles to that of Fig. 1.

Similar letters of reference indicate corresponding parts.

A is the balance-wheel; B, the ordinary treadle; O, the connecting-rod. D is a ratchet-wheel, which I propose to apply to the shaft of the balance-wheel, or to the wheel itself, with a pawl, E, pawl-lever F, retractingspring I, connecting-rod J, and a treadle, K, the treadle being arranged so that it can remain at rest or be worked together with the principal treadle when the machine is run-. ning, and can be worked independently of it, for starting the machine by raising the foot ANDREW N. HAGERTY.
